2) Potassium loss
钾素流失
1.
From the view of natural resource utilization and protection, a study on the principle of potassium loss under different land use patterns in a red soil watershed was conducted in Zhejiang province of southern China.
从资源利用的角度研究了红壤小流域不同利用方式土壤钾素的流失特征,结果表明,植被覆盖度低,无水保措施的试验区钾素流失量最大,封山育林,恢复保护性植被的试验区的钾素流失量最低。
3) potassium leaching loss
钾素淋失
1.
Dynamics of potassium leaching loss in three different purple soils and effect of N fertilizer rate, rainfall and temperature on K leaching loss were studied in a lysimeter experiment during the crop growing seasons in a paddy-rape rotation system.
钾素淋失量酸性紫色土(AS)>中性紫色土(NS)>钙质紫色土(CS)。

An experimental research on soil erosion and nitrogen loss under different vegetation cover;
不同植被对土壤侵蚀和氮素流失的影响
3.
Soil nitrogen loss processes resulted from rainfall and runoff were monitored in a small agricultural catchment of red soil areas in Jiangxi Province with the aim to investigate the relationship between the soil nitrogen loss and the corresponding rainfall and runoff.
以江西低丘红壤区农业小流域为研究对象,在自然降雨条件下对小流域内试验小区、上游灌渠和小流域出口径流中的氮素浓度进行监测,旨在从小区尺度和小流域尺度阐明农业小流域氮素流失与降雨和径流的关系。
6) nitrogen losses
氮素流失
1.
On the basis of water-nitrogen coupling balance theory and field observation results,a simple but comprehensive model was developed to predict nitrogen losses from a urea applied rice paddy field,considering all the important hydrological pathways such as surface runoff,lateral seepage,and vertical leaching.
基于水氮耦合平衡理论和田间实际观测,开发了一套既简单又综合的水田氮素流失特征模拟模型。
